Theleading objects of our improvement; are to provide improved devicesv for practically counterbalancing the weight of the beams and shovels and aid in lifting the same, and to provide an improved device for counteracting the 4o tendency ofthe shovels and beams to crowd either to the right or left, which we accomplish as illustrated in the drawings. Those things which we claim as new will be pointed out in the claims.|

In the drawings, A represents a split tongue of a cultivator, B, one of the wheels; O, the arch, having at each side a horizontal part, a, as usual, which parts a carry the wheels, and to these parts the forward ends of the beams 5o are connected. The cultivator is provided with two shovel beams andtwo gangs of shovels, only one of which are shown.

D is one of the shove1-beams, which is connected to one of the horizontal parts a of the arch, so that the shovels can have vertical niotion. As shown,this is accomplished by means ot' a sleeve and other parts.

b is the sleeve, which rotates ou a, and is provided upon one side with projections c.

d is an iron notched upon one side to correspond with the projections c.- It has an ear at each end. It is Vsecured in place by means of a clip, e, and boltsf.

E is a casting having a pin which enters the forward end ofthe beam, to which it is secured by bolts. 'The forward end of this cast ing has a long bearing to receive a couplingpin, g, which also passes through the ears upon the piece d. Thus the vertical and lateral movements of the shovels are provided for.

`7L is a projection extending up from the casting E.

Fis a lever, journ`aled,as shown, att' upon a.

j is an arm extending out from the upper end of the lever F, with which arm the projection h at the forward end of the plow-beam engages. This arm j may be regarded as a part of the lever F.

V7c is an arm .extending from the outer end of the arm j. lts lower end is provided with a lioolnwhich partially encircles the horizontal part a of the arch, the otlice or' 7a being to steady and support the arm j.

At the lower end of the leverF are two arms, one, l, extending forward, and the other, m, extending rearward.

cast together.

Gis a strong coilspring, the upper end of which is connected with a hook, p, upon the upper end of the bar n. The other'end, as shown, is secured to a short rod, q, which, as shown, is connected with a loose piece, r, which is pivoted tof the end of the arm m, so that in effect one end of the spring Gis connected with the upper end of u, and the other end with the arm m.

As shown, the iron o is secured to the frame by means of Va clip, s, which passes around. the arch and through one part of the split tongue,

The lever F, with the arms j k Z m, `may be as shown in Figs. i) and 10, Fig. l0 being a section at line .t of Fig. i). There are notches i on the sides of the piece o, which notches re ceive the clip s.

H is a coil-spring, the forward end of which engages-with a hook, u, at the outer end of a short bar, I, which is rigidly secured tothe lower end ofthe part (Z by means of a nut, r, ou. the pin g. The other end ofthe spring H is connected to a notched bar, J, which is shown enlarged in Figs. 14 and 1.5.

u; is a rod, the forward end of which is connected to the notched bar J, and the other end engages with an eye, a, on the under side of the beam.

b is a hook, on which the beam can be hung up when not in use.

K are braces.

c is a casting on the part n., held in place by a set screw, and located between the hub ot' the wheel and the arm t' of the part F. This part F swings freely on the horizontal part a, and has no connection with the sleeve b. The projection Zz, extending up from the casting E, passes inside of the bar 7:, which is a part of F, and ordinarily this part h comes in Contact with the inner surface ofthe bar lc.

It will be observed by looking at Fig. S that the coil-spring G- is not connected with the frame at either end, but that one end is connected with the upper end of the bar o1, the lower end of which bar is pivoted to the forward end of the arm or lever Z, while the other end of this spring is connected with the outer end of the arm or lever on., both of which levers l m are permanently connected with the lower end of the arrnj, which encircles and rotates upon a, so that the spring when under tension pulls down on the bar a, which has a tendency to force the lever Zdownward, while the other end of the spring, being connected with m, has a lifting tendency upon it. The spring G is to be so arranged that it will be under the greatest tension when the. shovels are down or in tlieground. 'Vhen the parts are in this position, the outer ends of the levers Z m and the part a will be in nearly the same vert-ical line, but not exactly, and in this position, though the spring is then under the greatest tension, it will have but little effect in counterbalancing the weight of the beam and shovels; but if the rear end of the beam be raised the position of thelevers Z m will he changed by the action of the spring, and its eiect in eounterbalancing the beam and shovels will be greatly increased. It will be seen that this spring G has a double action, lifting on the lever m and pulling down through the bar a on the lever Z. This spring acts upon the beam through the barj in contact with the projection l1. Il' the beam be returned to the position shown in Fig. l, the part h, engaging with j, causes F to partially rotate upon a, i11- creasing the tension of the spring; but the changed position of the parts at the same time decreases its sensible effect. XVe thus provide a spring which is not connected to the frame at one end, butis connected at both ends with devices through which the spring acts upon the beam. We are thus able to use a lighter spring than would be required if one end were rigidly secured to the frame, and obtain equally beneficial results. This spring act-s upon the beam through the two levers Zm, one of which extends forwardofand the other to the rear of the axle, or these two levers Z m may be considered as a single lever pivoted upon the axle at or near its center.

The spring H serves the purpose of counteracting the tendency of the beams and shovelsto swing to 011e side by the turning of a furrow. The rod w, 'to which one end of the spring is in effect connected, is attached to the beam. The other end is secured at a point considerably to one side of the center of the beaux, so that the tendency of the spring is to pull the beam to that side. The hook a might be placed upon the other side of the beam, and then the spring being attached thereto, its tendency would be to pull the beam in the opposite direction. The tension of the spring can be regulated by connectingone end in the different notches in the bar J. This spring H does not interfere with the movement of the shovels laterally to dodge plants out of line.

The advantages arising from the use of a lever, F, in conjunction with a spring for lifting the shovel-beam, can be utilized in other ways than thus far described.

Fig. 16 shows an arrangement in which the lever F and a spring operate on the beam without the use of the connecting-bar a, and with this form of construction the arm or projection Z is dispensed with, and the upper end of the spring is attached to an eye orv hook on the frame of the machine, or to some other suitable support, and with this construction the spring acts as a draw-spring to raise the lever and cause it to act on the beam. Fig. 18 shows another arrangement, in which the spring is caused to encirclea guide-rod, which takes the place of the rod n, the spring being engaged at its upper end with a collar or arm on the frame, and at its lower end with a pin or collar on the rod adjacent to the arm or proj ection Z, and in this construction the arm or projection on is dispensed with. The spring in this construction is a push one, to bear against the arm or projection Z to raise the lever and cause it to act on the beam. Fig. 20 shows another arrangement, in which the lever is attached rigidly to the beam-box and the spring and rod are both used, the arm for the spring being forward and under and the arm for the rod above the center of rotation, and with this construction the spring and rod act as irstdescribed.
